Water heater (291/365)

I need water heater, anytime anywhere. I am someone who is super afraid of the cold. even if i just came back on a very hot day. I will just cool myself down by not bathing immediately but i find myself turning on the heater. Of course i don;t bathe the super hot kind, but i need just that hint of eat in my water anytime of the day and anywhere i go. Especially when i go for an holiday. i need the heater in the cold col hotel room.
